Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a method for measuring the center coordinates of a structure. Background Art

[0002] During the construction of the inspection well, it is necessary to determine the location coordinates of the inspection well before construction can be carried out. After the inspection well is cast and formed into a structure, the coordinates of the inspection well need to be remeasured to confirm whether there are any displacements or deviations between the inspection well and the designed position. The traditional remeasurement is to use ropes tied in a cross shape to complete the inspection, but the cross-line-based remeasurement method can only roughly determine the position. Before the drainage pipeline trench is backfilled in the later stage, the Planning Bureau will usually send a specialist to conduct measurement and acceptance, and compare the measured data with the design drawing data after sorting out the actual measured data to determine whether the inspection well position deviation is within the allowable error range. The traditional remeasurement method often affects the project acceptance due to its low measurement accuracy. Summary of the invention
